If there’s one thing Star Wars fans love almost as much as Star Wars movies, it’s dressing up as their favorite Star Wars characters. Sadly, Storm Troopers won’t be welcome at many screenings when Star Wars: The Force Awakens debuts next month.

According to The Hollywood Reporter, various theater chains are announcing policies which would ban face-covering costumes and certain prop weapons, no doubt in response to a number of theater shootings in recent years.

“AMC does not permit weapons or items that would make other guests feel uncomfortable or detract from the movie-going experience. Guests are welcome to come dressed in costume, but we do not permit masks. In short, bring your lightsaber, turn it off during the movie, and leave the blaster and Darth Vader mask at home.”
